Hello, Aiosue.
Could you please help confirm the full model name of you motherboad?
Also, please try go to Intel(R) Ethernet Controller Properties> Advanced >select the Property "Energy Efficient Ethernet",
and select Value to "On (when system id in S0, S0c and Sx" to see if the problem can be fixed.
Thank you.
Due to the ongoing regional holidays, my responses may be slightly delayed.
Thank you in advance for your patience. 🙂
